prove the connection between the type bar 7 and the means for actuating it.-

and its actuating mechanism. F

' levers.

To the above and other ends, my invention resides in the features of construction and,

combinations of devices hereinafter more fully set forth and particularly pointed out in the concluding claims.

In the accor'n anying drawings, Figure 1 is a skeleton view 1n side elevation of a type bar 2 is a front elevation, partly in section, 0? parts of a typewriting machine illustrating my invention. Fig. 3 is an enlarged fragmentary topplan view of the pivot end of a type bar and its connecting link. 1 Fig. 4 is a view taken on the line a;a: of Fi 3. Fig. 5 is asec tional view taken on t e line y-y of Fig. 3.

Fig. 6 is an enlarged fragmentary side elevation of the upper portion of one of the subthe line z2 of Fig. 6. I

In the drawings, the reference 1 indicates the frame of the machine 2, the platen, 3, one of a seriesof key levers fulcrumed at 4 and each provided with a key cap 5 and a restoring spring 6. Pivoted at 7 to each key lever is a vertically disposed sub-lever 8, the lower end whereof is formed with a slot 9 which embraces a fixed fulcrum rod 10 which passes from side to side of the machine beneath the series of key levers and is secured in the base 1. The up er end of each sub lever 8 is "connected wit a type barll by a link 12 in a manner presently to bemore fully described. Each type bar is provided with-a type block 13 carrying one 'or more types, the forward end of said typebar normally contacting with a type rest 14 and "the rear end thereof being pivotally. secured to a hanger 15. The hanger 15 is onezof a radially ar: ranged series and is securedby a headed Fig. 7 is a sectional view taken on screw 16 to a segmental vertically-arranged support 1'7, said su sustained by' the si the frame 1.

port being guided and e guides 18 mounted on As best appears in Fig. 4, the rear upper portion of t e main central art of the type ar 11- is cut away at 19 an to each side 'of this rear portion is suitably secured a side member or check piece 20 (Figs. 3 and 5), preferably by rivets 21. The tail of the type ar, comprising three thicknesses or plies of metal, namely, the two side ortions or check- .pieces and themain centra portion, is erforated to receive the pivot pin 22,-w 'chpasses through the three plies of metal at pieces, and the ends of the earings in the ha er 15. he cheek ieces 20 are cut out or s aped to match su stantially the shape of the rear end of the central portion of the type bar, so as to produce a rigid and solid construction and one in which v there is a long seat orbearing for the pivot ref ivot have theirthe type bar, thus enabling the pivot to be] held securely in position. Insofar as the ball-and-socket joint is concerned, the cheek pieces 20 need not be made co-extensive'with the entire rear end of the type bar but only long enough or of a shape or size to rovide the socket portions for t e ball-shape end of the link.

Above the cut-away 19 .of the main central part of the bar the'inner face of each cheek piece 20 is recessedor depressed at 23 to receive the rounded, spherical or ballshaped forward end '24 of the connecting link 12. The rear 'ortion of the link 12 is flattened at 25 and as secured init-near its end a pin 26 formed 'with a head '27, the under or lower portion ofsaid head being flattened or cut away at 28.

'The upper end of each sub-lever 8, as appears most clearly in: Figs. G and 7,-is formed with an elongated slot larger in diameter at the lower end than atthe upper .and which for conveniencewillbe call key-hole slot l29. Secured to-thesub-lever belowthe key-hole slot in any suitable manner, as by a rectangular rivet 30, is a flat lockin spring 32, the free'end of which is bent inwar at 33 so that it normally stands within the ke -hole'slot 29 and terminates at a distance be ow the top of'said slot slightly greater the diameter of the'pin-26. Bythis arrangement, under any stress tending to cured in place on the type bar sn near'its free end with side it may be conveniently pulled away from withdraw the pin 26 from the slot, the head 27 of said pin is caused to engage with the face of the sub-lever 8 above the top ofthe key-hole slot, and thus the linkis prevented from being accidentally separated from the sub lever. The locking s ring is formed and thety e bar pivoted therein have been radially a justed: and secured, as seen'in Fig. 2, the connecting of each type bar may be turned in its recesses or sockets in the cheek piecesin said-type. bar until the I flat portion 25-is vertical, whereupon the pin 26 may be passed throughthe enlarged portion of the key-hole slot 29 ofits associate sub-leveror actuating member andllifted'to the upper narrow portion of said slot and a over the "free end of the spring, and thus Q locked'in lace .b "the latter, as'shownin d 7. The cut-away portion 28 of the head of the {pin enables the-top of the lockingspringte be arranged close enough .to the top of the'key-hole slot to" permit a Figs. 6 an snug fit otthe pin 26 tobe obtained',fthereby preventin looseness and rattle in the connection. y the employment 'of-this-construction, a considerable. saving; of time is eilected in assembling the parts of the type bar actuating'mechanism, asgziit is onlynecessary to-"snap each in 2 6 into place in the associate sub-lever a ter the arts have been a hove described, A.further advantage; is that as'the sides of the barisurroundin the pivot hole are in" mounted in the machine, as

thesame lanes-as-t e remaindHQLQf-Ithe rear portion o the type bar, Orin-otherwords; as the sides of th'e'bar at the pivotal end are perfectl flat, the pivot 22-may be adjusted or fitte therein w1th great accuracy. ;-W11i1e, I have shown my invention as embodied in.- the -Monarch typewriting machinefit is, of course, to baundersto'od that it may be applied to other formsof Writing machines and it'is further to be understoo that various changes in arrangement and construction of the arts jmay be efiected within the scopeof theinvention, and that 1 some parts of it may be usedlwithoutothers.

The ball-and socket connection between the type barfrand its associate connectinglink enables the latter to berevolved on its longitudinal :to any desired position.

ugs 34 by which ployed, whether that shown or some other, to iconnec't the link with the sub-lever or actuating member, the said link in any case may, without twisting or otherwise permanently alterin its original structure, be

revolved until it is in the proper position to be connected with its assoclate actuating member, this revolution being possible because of the fact that the link is substantially straight and its lon itudinal axis passes throu h the center of t e ball-carried at the end 0% the link.

It willbe noted that the type bars swing in radial lanes to. and from the printing point, whi ev the upright sub-levers vibrate insubstantially' vertical parallel planes. The rear end of each'connecting-link moves in an arc of a circle, thereby causing the pivot end of said link to move up and down. In the case of theoutsid'e type bar, as will be perceived from-an inspection of Fi 2, this up and down movement of the lin causes the latter to swing'nearly. straight across from .cne' cheek piece towards the other; while in the caseof the center type bar the up and down movement of the link will be in a plane parallel to the planes of the inner faces of the cheek pieces. In the case of the links of the type bars intermediate the center bar and the outside. bar,the movement varies between ,the two extremes. Furthermore, if there is ang loosenes's or other imperfections in the su -'lever or key lever set will be perceived, form-a trough .or open top box wherein the 'connectingilinkplays freely up and down or from side to side .or in an intermediate directipm. thereby allowing free movement-of the arts of the type action in Consequently whatever the .means .em Y

p at the upper end "of said sub-lever, instead of moving in a verv fltical plane, vibrates-in and out of said plane, the ball and socket 'oint permits such a lat- 1;.e1'hl movement to ta 0 place without causing any bindin the joint itself, The central portion-of each type bar and its cheek-pieces, it

any direction; an furthermoresaid link rotates. freely 'on its longitudinal. axis so that said link maybe connected with-itsassociate sub-lever without bending ortwisting either link or sub-lever. 1 a

- The herein shown and described construction of detachable joint betweenthe rear end of the link and-the upper en'dot the sub-lever is not claimed peras herein ,for the reason thatit is'the invention of EdwinE. Barney. What I claimas n w and desire to secure.
